I just upgraded to a SanDisk 32gb from my old 8gb and now i am missing a lot of my apps. They show in the app drawer, but when i try to open them i get the error that the app is not installed

You are making an erroneous assumption that a file by file copy would save you from having to reinstall apps. An sector by sector image would have been a better approach. One of the descrepancies between the old card and new is apparently leading the OS to conclude that the installed app files are no longer available.

It might be tied to a volume serial number or erroneous path, etc. But my guess would be that you missed copying a hidden system directory. In any event, try again or reinstall the apps.

Thanks for the response @fffft , i already formatted the old sd card and gave it to a buddy that has an s4 and had memory issues, with his kids installing every game they can find. Lol. I see a hidden folder that contains about 1.86 gb of data that looks like the files that i am missing, it seems that it was just copied to a different place on the new sd card, im trying to place it correctly, but if it doesn't work then i will just reinstall.
